Admin Dashboard 在 2.3.2 版本中失效

bpetty · 2019 年8 月 27 日 22:37

我刚将 Discourse 从 2.2.5 升级到了 2.3.2，但在处理管理员仪表板统计数据时似乎出现了回归问题，导致出现 500 错误，使我无法加载管理员仪表板。所有其他管理员页面（以及前端 Discourse 页面）仍能正常加载。

升级过程中我已运行了所有数据库迁移。

以下是我在错误日志中看到的错误信息和调用堆栈（我相当确定这就是导致 500 错误的相关错误）：

你好，

阅读堆栈跟踪后，我推测问题出在这段代码返回了 nil：

github.com/discourse/discourse

lib/discourse.rb

main


      
            assets << {
              name: "plugins/#{plugin.directory_name}_extra",
              plugin: plugin,
              type_module: false,
            }
          end
          
          if args[:include_admin_asset] && plugin.admin_js_asset_exists?
            if logical_path =
                 Plugin::JsManager.digested_logical_path_for(plugin.directory_name, "admin")
              assets << {
                name: logical_path,
                imports: Plugin::JsManager.import_paths_for(plugin.directory_name, "admin"),
                plugin: plugin,
                type_module: true,
              }
            end
          end
          
          if args[:include_test_assets_for]&.include?(plugin.directory_name) &&
               plugin.test_js_asset_exists?

DateTime.now - nil # TypeError: expected numeric

我觉得我们的代码在这里不够健壮，因为我们明知它可能返回 nil，却依然像它不可能为 nil 那样使用它。

@david 能否请您看一下？FEATURE: Display 'last updated' on dashboard, improve release notes l… · discourse/discourse@5666316 · GitHub

这确实看起来像是可能的问题。为了提供更多背景，我是在 Docker 容器中运行 Discourse 的（从堆栈跟踪中应该能猜到），但我并没有使用基于 docker-compose 的 discourse_docker 项目。我使用的 Docker 镜像直接从 GitHub 下载 tarball 发布包，而不是通过 git clone 获取，因此应用程序中任何基于 git 的逻辑都无法生效。

我已经很习惯仪表板中“已安装版本”字段不显示实际安装版本的情况了。这种情况从我有记忆以来就一直存在，不过至少之前它还没有导致仪表板崩溃。

出于好奇，这个功能是否有任何备用方案，可以从 git 以外的地方获取版本信息？如果没有也没关系，这并不会真的困扰我，毕竟无法从仪表板查看当前运行的版本并不是什么大问题。

这应该能帮你绕过该问题：
FIX: Allow dashboard to load even when git version cannot be found · discourse/discourse@ca9ef58 · GitHub

你可以在插件中覆盖它。但请注意，我们唯一支持的安装方式是此方式。由于你使用的是不受支持的安装方式，我们无法保证所有功能都能正常运行。

谢谢 David，如果在这方面遇到问题，我会联系你。
